Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

Instructor Comments, In-Person Week 5 Meeting, After POC Presentation, Thursday, 05/04/17

• • There may be less friction with the use of a crown pulley. Compensate for that.

    • Consider an "idler" to create more friction for the friction drive

  • Write about serviceability of Wire Storage in Final Report

Team Actions

• • Comments taken into consideration for design of Prototype 2

  • Discussion of Wire Storage serviceability

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Crown Pullies, 05/04/17

Risks and Areas of Concern

• • Time Risks (e.g. manufacturing of device and receiving shipment of parts on time)

  • Design Risks (e.g  design is prone to high failure rate)

  • Production Risks (e.g. prototype is impossible to manufacture)

  • Hardware Failure Risks (e.g. purchased components are incompatible with design or prone to high failure rate) 

  • Project Failure Risks (e.g. design is unable to work or be manufactured within the time-frame limit)

Resources or Information Required but not Available

• • N/A
